Giant Molecular Flashcards
1
Q
How are all the atoms bonded to eachother?
A
By strong covalent bonds
2
Q
Name a property they have
A
Very high melting and boiling points
3
Q
Do they conduct electricity?
A
No, expect for graphite
4
Q
What are they in water?
A
Usually insoluble
5
Q
Give examples of Giant Molecular Covalent Substances
A
Diamond and Graphite
6
Q
What are Diamond and Graphite made from?
A
Only carbon atoms
7
Q
What does each carbon atom form?
A
Four covalent bonds in a very rigid giant covalent structure, which makes diamond really hard
8
Q
Why does Diamond not conduct electricity?
A
Because there are no free electrons
